DockerGRPCMicroservicesPostgresRedisRuby on RailsRustWeb3

About the role

  • Design, implement, and maintain core components of the GraphTally protocol in Rust
  • Collaborate with researchers and protocol engineers to refine and evolve the architecture
  • Optimize signature verification, message processing, and batching for high-throughput performance
  • Implement secure state transition logic, trust-minimized payment flows, and smart contract interactions
  • Work closely with smart contract engineers to ensure seamless on-chain integration (mainly on L2s like Arbitrum)
  • Write clean, testable, and efficient code with a focus on security and correctness
  • Contribute to technical documentation, specifications, and developer tooling to support GraphTally adoption.

Requirements

  • 3+ years of professional experience writing high-performance, production-quality async code in Rust
  • Experience in designing and implementing remote APIs (REST, JSON-RPC, gRPC)
  • Experience in responsive microservices design and development
  • Experience with databases (Postgres, Redis)
  • Experience with Docker
  • Deep understanding of cryptographic primitives, especially ECDSA and digital signature schemes
  • Proficient with Rust’s async/await model, leveraging futures, tokio, or async-std
  • Understanding of asynchronous state machines for managing complex protocol flows
  • Familiarity with zero-knowledge proofs, state/payment channels, or escrow mechanisms is a plus
  • Strong grasp of trust-minimized systems, distributed protocols, or payment rails in a web3 context
  • Experience working with Ethereum L2s (like Arbitrum, Optimism) and integrating with smart contracts
  • Proficiency with testing, benchmarking, and debugging asynchronous Rust applications in the context of web3, using tools like anvil
  • Clear communication, curiosity, and a strong sense of ownership.
Benefits
  • Fully remote, async-friendly team with competitive compensation and token upside.
